LT1634CCZ-2.5#TRPBF

Voltage Reference Overview

The LT1634CCZ-2.5#TRPBF is a micropower precision shunt voltage reference with a fixed output of 2.5V in a 3-lead plastic TO-92 package. It provides an initial voltage accuracy of ±0.20% and a maximum temperature coefficient of 25ppm/°C. The device operates within a commercial temperature range of 0°C to 70°C, drawing a minimum operating current of 8µA at 10µA reverse current. It features low dynamic impedance and low-frequency noise.

Voltage Reference Feature Summary

• Utilizes bandgap reference technology with trimmed precision thin film resistors for high accuracy.
• Operates with extremely low quiescent current suitable for battery-powered applications.
• Stable with capacitive loads without requiring external output compensation capacitors.

Voltage Reference Applications

• Portable meters
• Precision regulators
• A/D and D/A converters

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the CCZ designation corresponds to the commercial temperature grade (0°C to 70°C) rather than industrial variants. Ensure compatibility with the TO-92 footprint during procurement planning.

Voltage Reference Selection Notes

Select this part when a stable 2.5V reference is required in a through-hole TO-92 package. It serves as a direct upgrade for legacy references like the LM185 or LT1004 where lower power consumption and guaranteed temperature drift are critical design constraints.

Voltage Reference Part Context

This component belongs to the LT1634 family of micropower precision shunt voltage references manufactured by Analog Devices Inc. The series offers various output voltages including 1.25V, 4.096V, and 5V across multiple package types such as SO-8, MSOP, and TO-92.
